WATER-COOLED CONDENSERS

Where sufficient water is available from city water supply, or where
a cooling tower is used. the water-cooled condenser is economical and
efficient. To match economically refrigeration load requirements. Westinghouse water-cooled condensers are available in 14 sizes. ranging in
nominal capacities from 2 to 100 tons net refrigeration effect.

WATER-COOLING UNITS

Vertical. semi-flooded type. Freon 12, water coolers for the chilling of
water for distribution to cooling coils in indirect air conditioning systems and for surface dehumidifiers. These efficient water-chilling units
range in size from 5 to 110 tons net refrigeration effect.

HEAT TRANSFER SURFACES

Direct expansion coils with patented refrigerant distributor. chilled
water coils, steam and hot water coils are available in a great many
sizes for all types of systems.

AIR CONDITIONING UNITS

Two types are available-a horizontal type for ceiling suspension and
a vertical type for floor installation. In the horizontal and vertical
types. year-round air conditioning is accomplished by the installation
of cooling and dehumidifying surfaces for summer, and heating surfaces for winter air conditioning.

AIR WASHERS

Three types are available*'l'ype H, with one bank of nozzles, used
primarily for humidifying; Type C. with two banks of nozzles, used for
evaporative cooling. humidifying and dehumidifying: and Type S.
with one bank of nozzles. used for humidifying, especially where
space is limited.

FILTER-WASHERS

Self-cleaning filter-washers employ a bank of mineral wool, or glass
fiber filter pads, in conjunction with water sprays to clean and
humidity the air. Made in 72 standard sizes and to specifications.

SURFACE DEHUMIDIFERS

Available for either chilled water or directly expanded refrigerant.
these wet surface units control accurately wet and dry bulb conditions
in industrial and comfort air conditioning systems. Capacities range
from 2000 to 50,000 cfm. with cooling capacities of 5 to 250 tons of
refrigeration.

PROPELLER FANS

PROPELLER FANS, DESIGN 7, with direct-connected motors. are generally applicable to all air exhausting or ventilating problems when
unit blows air directly outdoors or to another room, without ducts or
high resistance to air movement. Motors are totally enclosed special

fan duty type. Design 7 Propeller Fans are made in 7 sizes, from 12"
to 36" diameter. and 815 to 11,050 cfm.

CENTRIFUGAL FANS

SILENTVANER DESIGN 8. are high speed, exceptionally quiet heating
and ventilating fans engineered for installations where fan noise cannot be tolerated. Made in 21 sizes with rotors from lZI/4" to 87%" in
diameter. they operate from free delivery to 4" water gauge static
pressure. and at a maximum tip speed of 9000 feet per minute. Capacities range from 700 to 400,000 cfm.

PRECIPITRON* ELECTRONIC AIR CLEANER

This electronic air cleaner is designed for installation in the duct of an
air conditioning or ventilating system to remove air-borne dust and
dirt particles. with an efficiency of 900/o by blackness or discoloration
test. Made in sections. it can be applied to systems of 1200 cfm and
over. PRECIPITRON high cleaning efficiency reduces the cost of
redecorating and cleaning by removing dust and dirt particles from the
air which are too small to be removed by conventional mechanical
filters.

UNIT VENTILATORS

Unit ventilators filter. heat and circulate air through room areas. Each
unit is equipped with heating coil, a fresh air inlet. motor driven fans.
and controls, all enclosed in an attractive steel cabinet. Available in

auditorium type units for heating auditoriums and similar large room
area.
